3rd Gen Lift Pump

[BIGNASTY]

Good Morning Gentlemen

Nathan, BIGNASTY's Son here.

I have contacted My Dad who is having a wonderful time on Vacation ( I was under the impression that you got a vacation when you worked )

I have a problem with my Dodge (04 Stock HP) And its lift pump, mine is the OEM factory pump that's finally gone out on my truck. I asked Dad what kind of pump should I get to replace it?

He has an Airdog 100 with additional filters and has worked well for him for a long time. During our conversation he suggested that I get on-line and ask for your help. He mentioned that his choice of an Airdog may not be a good one any longer, some of you have voiced problems with the newer units.

I would prefer to stay away from the Factory Fix with installing the pump in the fuel tank, I would like to have the option for a better filtration using the filters of *My Choice* rather than have the need like My Dad, and install additional filters plus the ones on his Airdog 100.

I guess that what I'm asking are ideas for a stand-alone pump, so I can add filter heads with my choice of filter & water separation.


Thank You Very Much

Nathan

PS: Dad asked that you PLEASE!! help me out quickly, I'm using his Dodge until mine is fixed. :-laf

I can't comment on the air dog or others, but you can still get the lift pump that mounts on the back of your fuel filter housing from Geno's Garage. They are really easy to replace. I believe that better filtration is better but I just have been lazy and never done it. Others will give input on the other aftermarket pump options.

Nathan,

You said that you "would prefer to stay away from the Factory Fix" and that you "would like to have the option for a better filtration using the filters of *My Choice*" in the same sentence, so it seems that you may be suggesting that the one excludes the other. Nevertheless, from what I have read, the in-tank pump seems to be an excellent choice, AND there is nothing that will prevent you from adding your own filtration downstream.

From what I have learned on my CRD Jeep, it is best to keep the fuel under positive pressure all the time since the factory fuel-line quick connects often leak air when they are used for suction. By using the in-tank pump, your entire fuel line would be under positive pressure (relative to the atmosphere). You can add as many filters as you want between the tank and the engine. And if you get too much of a pressure drop, you can add another in-line pump to boost it back up.

And even, if you replace the pump with the original OEM style as CBari mentioned, you can still add better filtration, there really isn't that much of a nexus between "better filtration" and where the pump is.

I personally thing the FASS and AirDog systems are way overpriced for what you get and agree with you that I want the filtration to be my choice. When my OEM pump goes, I will likely go with the factory fix in-tank pump. In fact, I am seriously considering retrofitting my Jeep with a Dodge Ram in-tank pump.

375,000 mi on my FASS 150,they may not be the cheapest way to go,but with a little over403,000 mi on oem injectors,it was money well spent.i run the HF6604 and FS1065 filters

The in-tank fix is a great fix and one of the more reliable options out there.

If that wasn't an option I would look at the FASS, but keep the OEM canister too.

I would also add the heater option to it.

What My Dad was suggesting I do is use a stand alone pump like a Raptor from Airdog, run a Baldwin BF1212 water separator between the fuel tank and the pump intake. One of you that he calls the Filter Yoda (and trusts as sound info) said that the Baldwin prefers to have fuel drawn thru it rather than pushed thru it. From the lift pump to the OEM filter canister for some additional filtration and water removal, then to a Cat 2 micron filter just before the CP3 pump.

Dad said that the Raptor pump has been problematic from what some of the subscribers had posted.

Mr. BLNRAY

Dad's Airdog 100 is quite similar to your FASS 150, On his Airdog the best filtration is limited by what fits on the Airdog, With separate pump, fuel filter, water separator I can obtain better quality fuel.

I was just asking if anyone had an idea about a stand alone pump that actually works for the long haul.

Where we live if you breakdown it could be sometime before anyone sees your smoke signals, Because Cell Phones don't always work 200 miles from nowhere!!

I would also add the heater option to it.

Dad told me that your screen name was AH????? he cant remember names worth beans. I gather that your the one he calls the Filter Yoda?

The problem that he has with the in-tank fix is that you have to drop the tank to fix anything that goes wrong with the pump, he is all about ease of maintenance is why the separate pieces, Out of the tank.

I will run your idea about the in-tank to him. Meanwhile his truck runs Great!!


Thanks Nate

If you drop the tank put in the vent kit for faster fill ups I can give you info if needed. Also as mentioned above keep the canister you pull out in case down the line you go to a FASS .

 

[Prairie Dog]

I have a FASS but only because the OEM in-tank kit wasn't out yet. I would have much preferred the quiet, long lasting OEM setup.

 

[AH64ID]

Yes F/W seps do prefer to be on the suction side, but they do work on the pressure side.

I am undecided what I would do if my LP failed tomorrow. I like the service life and reliability of the in-tank, but a suction side f/w sep also sounds good.

I don't think you can really go wrong with either, and the current FASS has a heater option and uses good filters. I would do that over a filterless pump and extra filters, simply for simplicity.

Go with the FASS Titanium with the BF1212 and the 3 um on the FASS. That will pull the fuel thru the WS first then push it out the finer UM filter on the other end. AD has had so many CS issues it is hard to justify using them thought ther almost no differnece between them and FASS.

Mod your existing cannister to use 1/2 " suction lines fo the FASS will be happier.

If you use the good filters on the FASS and the best filter in the OE cannister that is excellent protection.

Get the heater probe option for the FASS, it is well worth it if you run in ANY cold weather. As big found out, you fill up down south and try to drive into the cold there will be issues.

Thanks I have talked to my Dad, (he talks I listen, is how it mostly works ) He liked the idea of the heater for the reason that you reminded him of. In South Dakota under a truck at Sub 0 temps is NOT a fun thing to do, especially for a Not so mechanically inclined person (that would be Me )

It looks as though I can obtain all the parts for this thru Thoroughbred Diesel unless you can direct me to a better source.

I Thank You for Your help, and all the other subscribers that submitted their ideas.


Dad said that he can Now!! go back to enjoying his Beer. Like He needs to be drinking a Beer, when tomorrow He my Mother & Aunt Louise are going Diving on the Great Barrier Reef. He repeated that fact several times until, I was sufficiently jealous. What an A Hole he is sometimes :-laf But we love him anyway.


Thanks Nathan

Another benefit of the FASS system is the lifetime warranty. It should be the last pump you ever need to buy. Send in the registration card as soon as you get the pump. Also a good idea to buy 2 sets of filters so you always have a spare set with you on road trips. Then when it comes time to do a filter change I use my spares and order another set to replace the spares.

I've been using the AirDog II 165 for about 4 or 5 years now. It works great, I can use Fleetguard water separator and fuel filters. the only issue that I've encountered is the pump motors themselves. I'm on the third one. All were covered under the warranty, but I had to replace 2 within the first 3 years of use. The newest one has lasted longer than the previous 2 together. It is also quite. I cannot say enough good things about it.

Sorry, while certainly I am glad that you like your fuel filter set-up, I can't really imagine highly recommending a manufactuer that made an item where I had to replace the main part of said item 3 times in 5 years. Just my .02

I tried to put a system together that would use a brushless motor just couldn't get the manufacturer to send me a pull off unit to work with . Would still like to pursue this rout as brushes suck .

I've got a friend in the aquaculture business. He uses pump motors for water that have magnets and a sealed impeller that spins, and is mounted to the motor. The impeller assembly has an intake and outtake side and fits over the end of the motor, keeping the motor completely separate from any liquid. When a motor burns out he replaces everything as a set, but in theory you could replace just the components that failed.

They have been using brushless solar hot water pump for years to supply V8 CP3's... Example supplier that doesn't use brass (Brass reacts with biodiesel)

They do burn up when run out of fuel.

 

[cerberusiam]

If these pumps are so great one has to question why they are not more popular. A little research provides an obvious answer, probably the reason why none of these type of pumps will ever catch on very well.

Ya Crunch I remember the Dynaflo pumps for the aquariums same principal .
